DIPTRACE ARDUINO SERIES
#1 Say NO to ARDUINO! New ARM Microcontroller Programming and Circuit Building Series – 12:02- BuildYourCNC If I need little to no external circuitry, then, aside from batteries, this whole thing could literally fit on a dime.īy the way, and unrelated to all that I just wrote, I finally came across a nice articulate introduction to the stm32 and its toolchain:
Since a lot of the energy goes toward just waking up the radio and getting it up to speed before it can receive anything, it may yet turn out that accepting a 1mbps on-air bitrate won't be too big a compromise, but I'd rather make that decision based on actual measurements rather than guesswork alone.īetween now and then I need to confirm that the BC805M has functioning DCDC circuitry in it, and I also need to measure the sleep current on the BC805M to make sure it won't be worse than expected with the integrated RTC running, which I'd like to use instead of a TPL5111 if the current drain will allow. So, in the interest of not getting detoured, when it comes to 2.4Ghz, I guess I'll just plow ahead using just nRF52 chips and see how low I can drive the energy consumption on an nRF52805 and still be able to wake it up with a radio packet. That's no good, because I want to use the faster 2mbps, which is almost the entire allure of using Nordic chips instead of something else. It turns out there does still exist regular, non-enhanced Shockburst which the nRF24L01 can still use and which doesn't have the oddball 9-bit PCN, but then the maximum transmit speed of an nRF24L01 is limited to 1mbps. That said, I think it probably can be done, but it would maybe turn into a long detour that I'd rather not take right now.
DIPTRACE ARDUINO HOW TO
I have nRF52805's and nRF52832's talking to one another using the proprietary radio, and I obviously have nRF2401's talking to one another, but getting the two groups to talk to each other? It's not obvious how to do that: Enhanced Shockburst of the nRF24L01 has a weird 9 bit section called PCN in the middle of it, and it's not clear how to get an nRF2 to receive that kind of oddball frame without rejecting it.
